Folded to increase surface area for absorption thin epithelium to reduce distance of diffusion micro-villi on inner lining to increase surface area for absorption folded to reduce speed of ?ow for efficient absorption numerous mitochondira to provide energy for re-absorption dense capillary network to transport reabsorbed products
The cells lining the tubule have numerous mitochondria which provide the energy required in the form of ATP molecules.
Cells of tubule have microvilli which increase the surface area for selective reabsorption.
The tubule is long and highly coiled to provide a large surface area for selective reabsorption.
The coiling of the tubule reduces the speed of the flow of the filtrate to give more time for efficient reabsorption.
The tubule is well supplied with blood capillaries to increase a steep diffusion gradient for selective re-absorption.
